温排水对水体环境影响的数值模拟

Numerical simulation of thermal discharge on water environmental impact

电厂冷却水的合理排放和排放水体的温度预测能为水体环境影响评价提供科学依据。采用平面二维水流温度场数学模型,对池州电厂的温排水流场和温度场进行数值模拟。在流速验证的基础上,考察温度场的分布情况。分析结果显示,池州电厂二期扩建后的温排放对保护区及周边水体不会产生明显的热影响。

Rational drain of power plant cooling water and temperature prediction of receiving water can provide some scientific evidences for EIA of water body. The flow field and the temperature field of thermal discharge in Chizhou Power Plant is simulated by adopting the mathematical model for two - dimensional flow field and temperature field, On the basis of flow velocity verification the distribution of temperature is surveyed, The analysis result shows that the heated discharge from the second period of extension in Chizhou Power Plant will not bring remarkable thermal effect for protected zone and peripheral water.
